Abstract: METHOD OF HEAT TREATING NICRALY ALLOYS FOR          USE AS CERAMIC KILN AND FURNACE HARDWARE                       ABSTRACT           This invention relates to components of ceramic kiln and furnace hardware made of NICRALY alloys.         Disclosed is a method of heat treating NICRALY alloys to obtain a uniform film of desired alumina (Al2O3) on the surface of the alloys.  The gist of the invention resides in the control of the critical relationship between the tempera-ture and the partial pressure of oxygen in the oxygen potential controlled atmosphere during the heat treatment.  Optimum results are obtained when the temperature is about 2100°F (1150°C) and the dew point is about -30°F (-34°C) in hydrogen for about one hour.

Abstract: METHOD OF MAKING AND USING NOVEL SCALE INHIBITING TERPOLYMER                   ABSTRACT OF THE DISCLOSURE A two-step process is disclosed for preparing an essentially non-crosslinked random copolymer of acrylic acid or methacrylic acid with esters of the acids which esters are formed by reaction with an alkylene oxide. Raw materials, are (meth)acrylic acid and alkylene oxide. In a first step, a predetermined amount of a particular esterification catalyst is used, and with close control of process conditions, the (meth)acrylic acid yields both mono- and polyalkoxylated esters. In the second step polymerization is effected without separating the esterification catalyst or purifying the esters formed. The resulting random copolymer formed consists essentially of a terpolymer of (i) acrylic acid or methacrylic acid (together "(meth)acrylic"), (ii) a hydroxymonoalk-ylated (meth)acrylate, and (iii) a hydroxypolyalkyleneoxylated (meth)acrylate the monomeric moieties being present in specified relative proportions. Despite the presence of the polyalkyleneoxylated ester moiety the terpolymer is soluble in water, and is surprisingly effective in the treatment of industrial process water used in recirculating water systems.
